9 Sensor resolution
Image resolution can be measured in various ways like spatial, spectral, temporal and radiometric. Based on these parameters image resolution is categorised into following four types:
• spatial resolution – it refers to variations in the reflectance/emittance determined by the shape, size and texture of the target
• spectral resolution – it infers changes in the reflectance or emittance as a function of wavelength
• temporal resolution – it involves diurnal and/or seasonal changes in reflectance or emittance and
• radiometric resolution – it includes changes in the polarisation of the radiation reflected or emitted by an object.
